Since it is a lot of work to keep this structure up-to-date manually, PulseAudio can do that automatically for you: if PA_STREAM_AUTO_TIMING_UPDATE is passed when connecting the stream PulseAudio will automatically update the structure every 100ms and every time a function is called that might invalidate the previously known timing data (such as pa_stream_write() or …

As an optimization for avoiding needless memory copies you may call pa_stream_begin_write() before this call and then place your audio data directly in the memory area returned by that call. Then, pass a pointer to that memory area to pa_stream_write(). After the invocation of pa_stream_write() the memory area may no longer be accessed. Any further explicit freeing of …

At the moment (high level) a callback is setup using pa_stream_set_write_callback() and then there is a main loop running over pa_mainloop_iterate(). The issue is there is a significant delay (~280ms) before my callback is called (i.e. the stream is writable) and this it is obvious that the audio is out of sync to the light event.
